Swamp's topographic "slight of hand"

By check I mean cross-check to make sure what they are showing matches up with what is actually there in the field.

Hydrographs need to be field checked

On this particular trip I was focused on the pond apple.

My hydrograph showed them to be dry, i.e. water levels had dropped about a half foot below the pond apple forest floor. I was happy to visually (and in first hand) confirm that my hydrograph was correct, or mostly correct. One spot showed pond apple to be plentiful in what appeared open water.

I was baffled:

Could the pond apple really be that wet?

Pond apple took root on tussockswhere once was just open water

The trick was they had taken root on slightly elevated micro-islands of peat, rock and old tree stump remains called tussocks.
